SPARE-TIRE-LOCKING DEVICE.

Application filed '.Tu1y;12, 1923. Serial No. 651,011.

To all whom it may conce-m.'

Be it known that I, CoLvIN L. JoHNsoN, a

of reference marked thereon, whiclrform aV part of this specification.

This invention relates to-4 an improved type of spare tire locliing device, *in which l the cost of manufacture is materially reduced and `wherein the lmanufacture vand assembly is simplified.

It isan object of this invention'to provide an improved method of manufacturing and assembling spare tire locking blocks.

It is l also an object of this linvention to provide an improved spare vtire or wheel lock wherein `the latchbolt is slidable in a guide sleeve positioned withina closed bore of a lock block for co-action with .an armored cable, said bore being positioned at right angles'and in'thep'lane `of three parallel drillings lmade longitudinally in the lock block. n

It is an importantfobjectfofthis invention to provide `a sparetire lock block which may be readily drilled to Ypermit the locking members and anr armored cable tobe quickly mounted inposition to provide'a spare tire lock.

Other and further important objects of this invention will be apparent from the disclosures in the specification and accompanying drawings. i

This invention (in a preferred form) .is illustrated in the drawings-.and hereinafter more fully described.

On the drawings: A'

Figure 7 'is a transverse detail' section taken on line 7--7 of Figure- 2. i

' Figure 8 is a detail view ofthe lrey loclr protecting cover taken on line 8--8 of Figure 7 As shown on the drawings:

The reference Vnumeral 1 indicates a tire support having-mounted thereon a spare tire 2 which is locked in. place by a tire lock of this invention. The tire lock comprises an armored cable formed of a stranded cable or rope 3, preferably of steel or other flexible wire, having "terminals 4 and 5 attached to the ends thereof. yIntermediate the terminals .4 and 5 are arranged a series of interlitting armor members @having shoulders 7 formed thereon.

The armored cable is `used in connection with a metal block 8 made of high grade steel and having rounded ends and fiat top and bottom surfaces. The block 8 isdrilled to provide a pairof parallel cable openings 9 and 10 and with a lock chamber or recess 11 which is alsowparallel to the openings 9 and 10. The openings 9 and 10 extend through the block while the opening l1 eX- tends abont'half waythrough the block and communicates with a bore `or opening y12 drilled in the block yin the plane of the openings' 9, 10 and v11, but at right angles thereto. The inner end ofthe opening 12 opens into the opening 9. The' block S is thus provided `with four openings or drillings which may be conveniently drilledV in the block at a small expense. v s

Secured inthe opening 12 is a guide sleeve 13' of suitable contact metal within which a latch bolt 14 ispositionedto slide. `A circular plug or closure plate 17 which is shaped to conform to the shape of the curved end of the block 8 is secured in the outer end of the opening 12. The closure plate 17 is retained in place by means of a pin 18 to seal the outer end of the'opening 12. The end of the pin 18 is ground off flush with the bottom surface of the block 8.

The latch bolt 14, when in locking posiv the armored cable locked against retraction from the block 8.

The latch bolt 14 is provided with a transverse slot or groove 20 (Figure 4) into which pro-jects a pin 21 which is secured eccentrically on the inner end of a rota-table lock barrel 22. The barrel 22 forms part of a key lock 23 which is mounted in the block opening 11. The lock barrel 22 is provided with a key slot which is normally closed by means of a closure cap 24 pivoted upon the top surfaceof the block 8 by means of a pin 25. A spring 26 is mounted within the cap 24 to normally hold the cap 24 in a closed position to cover the lock key slotand so protect the same from dirt and the like. As shown in Figure 2, the sleeve 13 is provided with an opening 27 through which the lock barrel 22 projects.

Then the armored cable is looped aro-und a spare tirel or other article on the tire support 1, the end 5 of the cable is pulled through the block opening 9 until the enlarged end of the terminal head 4 seats in the reamed out end of the block opening 10. During the pulling of the armored cable through the block openings, the latch bolt 14 is forced into retracted position with the passing of the cable links. The latch bolt may be retracted by means of a key to ermit withdrawal of the vcable through the block opening`9. The sleeve 13 in the block 8 affords a suitable guide for the latch bolt and may be made of babbitt or other suitable bearing material. c

The method of manufacturing the spare tire lock is simple and inexpensive, andthe parts are adapted to be readily assembled. The block is first drilled and reamed to provide the openings 9 and 10, after which the opening 12 is drilled in the block, to communicate with the opening 9. The recess 11 isk next drilled in the block to communicate with the opening l2; When the blockis drilled the sleeve 13 and the latch bolt 14 are placed Within the block opening 12. The closure plate 17 is rigidly secured in place by means of the pin 18. The key lock 23 andthe armored cableare then molrmted in place to provide the finished loc I am aware that numerous details of construction may -be varied through a wide range without departing froml the principles of this invention, andI therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as "my invention: y

1..A spare tire lock comprising a block having three parallel openings therein and a recess connecting two of said openings, a

with the latch bolt to permit operation thereof, and a spring controlled covery mounted on said block for covering the exposedy end of the key lock.

2. A lock of the class described comprising an armored cable and a latch mechanism, a block supporting the same having openings drilled therein, two of which are connected by a recess drilled in said block at right angles to said openings and connecting two of the openings, said recess having the latch mechanism disposed therein, ay platejin said recess flush with the outer surface of the block, and a pin projecting through the plate and projecting into openings in 'said block to rigidly hold the plate secured in said recess to close the same.`

3. A spare tire lock of the class described comprising a block having a plurality of drillings therein, an armored cable engaged through two of said drillings, an apertured sleeve in another of said` drillings, a latch boltin said sleeve, means for sealing up the outer end of the rdrilling in which said sleeve isldisposed, and a key lock in still another of said drillings projecting through the apertured sleeve to engage the latch bolt to permit operation thereof into and out of engagement with the armored cable. In testimony whereof I have hereunto j subscribed my `name in the presence of, two

subscribing witnesses.
